Auto-negotiation Monitor Bits
These bits are for debug only. The auto-negotiation status will be
written to these bits.
Reserved
Read as 0, ignore on write
Link Pulse Enable
1 = Transmission of link pulses enabled
0 = Link pulses disabled, good link condition forced
This bit is valid only in 10Mbps operation
Heartbeat Enable
1 = Heartbeat function enabled
0 = Heartbeat function disabled
When the DM9000A is configured for full duplex operation, this
bit will be ignored (the collision/heartbeat function is invalid in
full duplex mode), This bit is valid only in 10Mbps operation.
Squelch Enable
1 = Normal squelch
0 = Low squelch
Jabber Enable
Enables or disables the Jabber function when the DM9000A is in
10BASE-T full duplex or 10BASE-T transceiver Loopback
mode
1 = Jabber function enabled
0 = Jabber function disabled
Reserved
Force to 0, in application.
